Courses - Microsoft Excel 231
Description: Intermediate Microsoft Excel
Running Time: 78 minutes
Pre-Requisites: Excel 230 strongly recommended
Versions:
We use Excel XP in this course, but the lessons are valid for all versions of Excel from 95 to 2003. There are cosmetic changes in Excel 2007. Order before 11/24/2019 to get a FREE upgrade to our 2007 version when released!


This course covers mostly error handling - dealing with all of the nasty errors that Excel throws at you like #NAME? or #REF!

We also go into logical errors... things that are wrong with your spreadsheet but not necessarily things that generate an error message. These are even harder to track down.

I'll teach you about errors with rounding numbers, and how to force Excel to round values off with the ROUND function. I'll also show you some instances where Excel is just dead WRONG with it's calculations.

You will learn about all of the different logical functions, like TRUE, FALSE, NOT, AND, and OR, and how they work with your IF function to create much more powerful statements.

We will then take a more detailed look at the Auditing Toolbar. No, this has nothing to do with the IRS. You'll learn how you can track down your errors by tracing the precedents and dependents of each cell (which other cells are responsible for it's data - and which depend on it for their data).

You will learn about the powerful Evaluate Formula toolbar that allows you to step through a complex calculation and see Excel evaluate each part. You'll also see how to Circle Invalid Data, and use the Watch Window.

Next, I'll show you how to hide errors on your printouts, and how to turn Automatic Error Checking on and off. You'll also learn about Circular References: what they are, why you don't usually want them, how to fix them, and when you might actually WANT them. Essentially, you can use a programmer's trick to use Circular References as a DO LOOP.

Finally, I've got a few Tips & Tricks for you... how to transpose your data, how to use the Fill command (like Autofill, but with a few more options), and so on.

This is a good class. It might not seem as exciting as charting or pivot tables, but there is a lot of good, solid information in this class that will make you a better Excel spreadsheet designer. Lots of fundamentals.
